I’m looking to do some work in my (incredibly dated!) kitchen; wondering if anyone would have a rough idea of cost for removing the brick housing around the oven and cutting a hole in the wall behind to add a breakfast bar (pics attached). I live in a ground floor apartment and don’t believe that wall to be load bearing though I obviously will confirm before doing any work.
My first plan was to remove the walls and open it all up but that’s off the table now. The kitchen backs onto a large entryway that’s mostly unused so having some seating there isn’t a big deal.

After a year of this incredibly cramped and really not ideal former-commission-housing space, I need a change!
Kitchen would be gutted, with a rectangular hole cut behind the pantry. The door has already been removed.

This is all solid af; assuming it’s brick as is the rest of the interior.

Scrappy sketch so you can see what I’m on about.
Thank you in advance for any replies!
